AXIS Q6032 PTZ Dome Network Camera
Video and Audio
Note
A multi-connector cable (available from Axis;
Multi-Connector Cable (sold separately)
) is required when connecting external
audio equipment to the Axis product.
Source - Select Microphone for an external microphone or Line for a Line in device, e.g. an audio mixer for multiple microphones or
a microphone with a built-in amplifier.
Microphone power - The Enable microphone po wer option provides DC power for an external microphone. Microphone power
should only be used with microphones that have no battery. This s etting should not be enabled when using a dynamic or battery
powered microphone. Microphone power will not harm the microphone; if you are uncertain, try switching it off and on. To use a
professional microphone requiring 48V phantom power, y ou need an external power supply a nd a balanced-unbalanced converter
(audio transformer) in between.
Input gain - Control the volume (dB Full Scale) of the audio inp ut. If the sound is too low, choose a higher dB, to amplify the
sound. If the sound is too high, choose a lower dB. The Level bar gives a visual repres enta tion of the audio signal level in dB
relative to the full-scale input level.
• G reen — the signal is at a good level.
• Yellow — the signal is becoming distorted.
• Red — the signal is distorted.
Encoding - Select digital audio encoding format.
• AAC requires a license for both encoding and decoding. AAC is the least complicated and most widely used codec.
If achieving the best possible audio quality is a priority, A AC is the recommended codec to use. An A AC license
is included in the A xis product.
• G711
• G726
Sample rate - The number of times per second the sound is sampled. A higher sample rate will provide better audio quality, but
also requires a greater bandwidth.
Bit rate - Set the required bit rate depending on the s
elected encoding. A higher bit rate will give better audio quality. A lower bit
rate may have latency or delay, but will require less bandwidth.

Audio Output
An external speaker can be connected to the product’s Audio -out connector (a built-in amplifier is required for this). The output can
be connected to another am
plifier with speakers. A stereo connector must be used for the audio out.

tput settings under Video & Audio > Audio Settings.
